Business app development. From £6,000.
Custom web and mobile applications for businesses in the UK, US and Germany. A senior engineer scopes and builds your customer portal, internal platform or business product. Packages start at £6,000, with the final scope and fixed fee agreed before work starts. Your cloud, your code, and a handover your team can use. Cloud and model running costs are separate.
What this covers
Web and platform engineering
Customer portals, dashboards, marketplaces and internal platforms built to carry real operational traffic.
Mobile experiences
Mobile applications that share a backend and a data model with the web product instead of drifting apart from it.
Backend and data platforms
The APIs, data model, storage and job processing underneath, designed for the load the product will actually see.
AI capability inside the product
Assistants, extraction, ranking, matching and generation, built as product features with evaluation behind them.
Cloud architecture and deployment
Infrastructure, environments, CI and observability, so releasing is routine rather than an event.
How we approach it
-
01
Model the domain first
Most product pain later traces back to a data model decided in a hurry. We spend the time there before writing feature code.
-
02
Ship thin slices end to end
A narrow path working from interface to database beats a wide set of half-finished layers, and it lets you see the product early.
-
03
Treat AI as a feature with a spec
Anything model-driven gets an evaluation set and an accepted quality bar, so it can be improved deliberately rather than by feel.
-
04
Build for handover from the start
Conventions, documentation and tests exist so your own engineers can pick the product up.
What you end up with
Every engagement is scoped to an agreed outcome and quoted as a fixed fee, so you know the cost before work starts. For a founder-led company that is the whole product; for a team inside a larger organisation it is usually one internal platform with a handover to your own engineers.
- A product in production, not a demo environment
- Web and mobile sharing one backend and data model
- Infrastructure, environments and deployment set up properly
- Evaluation behind the AI features, so quality is measurable
- A codebase your team can take over
Get a fixed-fee scope
Describe the product and the business it serves: who will use it, what it replaces, and what it costs you today. You will get a considered reply from the engineer who would build it, not a brochure.
